7 Claims. (Cl. 20 62) I This invention relates to pivotable louvered window construction and, more particularly, to jalousie structures in which the louvers each embody plural panesor panels arranged in a common louver "frame 'in parallel and spaced-apart relation.

An object of the invention is to provide a jalousie window structure wherein the louvers are pivotable to an open position effective to pass air but inhibiting the entry of rain therethrough.

Another object is to provide a double-paneled jalousie window which will be efficient in use andpsimple and compact in assembly.

A further object is to provide a pivotable-louvered window structure which may be readily and economically fabricated. l

Yet another object of the invention is to provide a double-paneled jalousie window having, when the louvers therein are closed, an air space intermediate the inner and outer panels whereby to promote thermal insulating characteristics residing in the window structure.

These and other advantages of the invention will be discernible from the detailed description thereof hereinafter set forth.

According to the invention, the window structure comprises a frame in which is arranged a plurality of superposed louvers having oscillatory movement on horizontal axes between open and closed positions. Each louver has a pair of parallel panels supported at the ends thereof in individual end brackets common to each pair, and the panels of each pair are spacedapart to provide an air space or passage therebetween. The louvers are so constructed and arranged, relative to the frame and to each other, that they are pivotable to an open position wherein the inner panel of one louver is inclined in substantially a common plane with the outer panel of the louver therebelow and in contiguous alinement therewith, the abutting panels forming a baffle adapted to exclude rain but permitting the passage of air therethrough.

Interposed between abutting marginal edges of those panels constituting this bafe, are resilient strips effective to provide weathering closures therebetween and at the same time impart a yieldable characteristic tothe edges of the panels whereby to insure the operational clearance between adjacent louvers` in passage through their respective paths of rotation. l

The invention is embodied in a jalousie structure exemplified in the accompanying drawings in which the views are as follows, like reference characters designating identical or analogous parts throughout the several views:

Fig. 10, a front elevation in part of the window; and

Fig. l1, a fractional front elevation of the window shown in section in Fig. 9.

Referring now to Figs. l and 4, the jalousie structure has a frame comprising a head 1, a pair of opposed jambs 2 and 3, and a sill member stepped at two levels 4 and 4 and yincluding an upstanding intermediate dwarf wall 5 extending from jamb to jamb for a purpose to be presently set forth. The frame includes the usual marginal trim members, there being a sill front trim 6 and rear trim 7, jamb front trims 8 and rear trims 9. The

head includes a downwardly directed front trim member` Arranged between the jambs, is a plurality of louvers each comprising an inner panel 11 and in parallel relation thereto an `outer panel 12 spaced therefrom to provide an air space or passage therebetween. i

The inner panels 11 (Fig. 2), have a top rail 13 generally defining a downturned channel, and a bottom rail 14 generallydescribing an H-shape in cross-section. Between the opposed upper and lower grooves thus formed, a glass pane P which forms the body of the inner panel 11 is received. The outer panels 12 have a top rail 15 generally defining an H-shape in cross-section and a bottom rail 16 in the'form of an upturned channel in crosssection. Between opposed grooves thus formed is received a glass pane P defining the body portion of the outer panels 12. A modification from the foregoing rail patterns resides in the topmost louver wherein the top rail 17 in the outer panel and, in the lowermost louver the bottom rail 18 in the inner panel, respectively assume downturned and upturned channel forms as clearly shown in Fig. 1. l

Arranged at the ends of each louver for the common support of the inner and outer panels embodied therein (Figs. 2 and 8), is an end bracket having an end wall 19 against the inner face of which are formed an inner pair 20 and outer pair 21 of inwardly projecting flanges respectively adapted to receive the side marginal edges of the panesy P and P.

Flanges 20 and 21 constitute corresponding side rails which may be separably 'united in any manner conventional in the art with the vtop and bottom rails hereinabove described whereby to form thel marginal frames within which the panes P and P may be removably supported.

End walls 19 are pivotably connected by pivot pinsv ranged at each side of the frame and reciprocable in a vertical path to which each bar is confined by a pair of outwardly aring marginal flanges 24 extending alongy the outer face of the bar and adapted to travel in complementary upright slots 25 provided in the adjacent jamb structure.A Introduction of bars 23 into the slots 25 may be effected, where the frame assembly does not otherwise permit, through convenient apertures provided in either the head or sill members of the frame.

Fashioned against the rear exposed edge of each bar rack 26` inmeshwitha pinion 27 xed-upona stub shaftM 28 and rotatable thereby to impart reciprocal movement to the bar 23. The stubsliaft, journaled as at 2,9 in a suitable bearing formed i'n adjacent jambf structure, is rotatablev by'A aP drivempulley' 30's fixedV thereon andconnected: througlra'fbelt'cable 3-1 with a-'drivepulleyiSZL mounted (Fig. 6) upon a main shaft 33 therebelow'fprtheftrinr member 7 through which the shaft projects to. receves'thereona crank 38: At'the opposite end thereof..

the shaft 37 is. j ournalcd in a bearing 39 fastened tothe adjacent 4face of the intermediate wall' 5'.' A suitable housing 40; carried by the` trim member' 7' against the.

inner face thereof,may enclose the worm. Wheel' assembly and provide support' therefor inY amanner well known in the art. l

The louvers are each operably connected toy bars, 2.3 by a link 41 pivoted` at one end. to the, bar and' at..the opposite endA to. a bracketA 42 fastened against. the inner faceof'adjacent rail structure forming the upper margin of" the inner, panels IIv whereby,- reciprocal-v movement. of the bars 23 is seen to. oscillate the louvers on. thepivot pins Z2.

Upon, turningfthe crank 38, oscillatory movement is imparted tov the louvers. and; the panels incorporated therein tlrrough intervening. operating mechanisms. here: inaboye described.

Again referring to Fig.. l., the inner and outer panels intheir. respective planes are. staggered relative` toeach other according to a stagger interval which disposesthe outer. panels each at.a,predetermined. lower elevationrelative, to the, inner panel. corresponding thereto. The. spacing adopted betweenl the inner and outer panels, the height of -the panels, and. the. stagger interval thereof may bedmesionedso as to provide a construction and, arrangement of louvers which, when pivoted to an open4 position inclining the louvers at a given angler bring thebottom. edges of the inner panels into substantial engagement with the top edgesof the outer vpanels in the .louvers respectively next therebelow.

The. louvers thus are pivotable. to an open position shown in phantomV in whichV the inner panels` 11,., exceptA that in the lowermost louver, are inclined in substan tially a common plane with the. outer panels 110i the louvers next therebelow and in` contiguous 1e1a1ti.0.121,tljlere.-v to. The abutting panels will be seen to constitute a bathe fronting the window opening and functioning to exclude rain therefrom. At the same time, the passages designated A intermediate the inner and outer panels function to circulate air between the louvers.

Thus, interior spaces having communication with atmosphere through a jalousie structure; tovWhiCh the prin.-` ciplcv of the invention is applied mayreceive ventilation while rain is excluded therefrom. Y

Referring now to Figs. 2 and 3, the panels constitut ing the baflleherein described, now styled thebafe. panels, include substantially arcuate weatherstrips 4,3. interposed therebetween. TheseVV strips, fabricated from any spring-like material possessing suitable characteristcs of tension and; resiliency, may be preformed to apprmtimatey a. U-shape crossfsection; therethrough. One leg or Vfrange is. fastened Vas-byspot welding or threadable fastenings to' the'inner f at, 0f; the .Hshap1; abut?. ting railsI in the bae panels, as.` at; Figi 3'.

The width of the strip may be pre-determined relative to the depth of the grooves G, whereby the loops L intervening between anges F and F are yieldably engageable with corresponding loops opposed thereto when the bafe panels are inclinedtovform the baie hereinbefore described..

Thus, by virtue oftheres'ilient weatherstrips 43, the louvers in their closed positionsl and the baille panels in their inclined positions are provided" between .abutting elements; with a. Weathertight 1'0inIu.r.e.- The resilient characteristic residing in these weatherstrips insures operative clearances between-adjacenelouvers in their respective paths of rotation. The end walls 19 may have rounded 01T portions as at 44 and 45 to assist as may be necessary in eectingrthe forego-ing operative clearances.
